Unknown Liquid: My Thought Experiment on What Could Be Fundamental

1. What I was actually wondering (introduction)

I started thinking something simple but confusing.

Everything we see—solid, liquid, gas—keeps changing form. Water becomes vapor, vapor becomes liquid again. Nothing really “disappears”; it just changes shape.

So I asked myself:

If everything is just changing form, then what is the original form?

Then I started wondering if the Big Bang itself could have come from something that is not empty space, but something like a “liquid-like medium” that already existed in some form.

Not normal water — something unknown, something fundamental.

2. Why I thought about “liquid” in the first place

Because liquids feel like they are “in-between states”.

Solid → rigid
Gas → fully free
Liquid → in-between, flexible, adaptive

So I thought:

What if the universe itself started from this “in-between state”?

Not a solid object. Not empty space. But something that can change form.

3. Where my confusion started (important part)

Then I started questioning:

If something like this exists, then why don’t we see it directly?

Because in normal life:

Distilled water is “pure”
But it does not create anything new by itself
Impurities (ions, particles) change behavior

So I thought:

Maybe “creation” needs some kind of internal structure or “activity” inside the medium.

That led me to imagine:

What if the early universe was not empty, but had some kind of active medium already inside it?

Not just passive matter — but something that reacts, collapses, or expands.

4. Mathematical / Computational Model (Conceptual)

Let the Unknown Liquid be represented as a dynamic non-equilibrium field system, where physical properties are not constants but emergent functions of internal state and external conditions.

4.1 Dynamic Viscosity Function

V(t, p, T, \sigma) = f(\theta(t))

Where:

$t$ = time evolution parameter
$p$ = pressure
$T$ = temperature
$\sigma$ = applied external stress
$\theta(t)$ = internal latent state variable governing microscopic configuration

👉 Interpretation:
Viscosity is not fixed; it is controlled by an internal evolving state rather than only external thermodynamic conditions.

4.2 State Transition Probability Model

P(S_i \rightarrow S_j) = \frac{e^{-\Delta E_{ij} / kT}}{Z + \epsilon}

Where:

$S_i, S_j$ = discrete material states
$\Delta E_{ij}$ = energy barrier between states
$kT$ = thermal energy scale
$Z$ = normalization (partition function)
$\epsilon$ = instability perturbation term

👉 Interpretation:
State transitions follow thermodynamic probability, but include an instability term $\epsilon$ that introduces deviation from classical equilibrium behavior.

4.3 Instability Threshold Function

\Phi(p, T, \sigma) > \Phi_c \Rightarrow \text{state collapse or transition}

Where:

$\Phi(p, T, \sigma)$ = combined instability field
$\Phi_c$ = critical threshold

👉 Interpretation:
When environmental stress crosses a critical boundary, the system does not change gradually — it undergoes abrupt phase transition or collapse.

5. My working idea (simplified model)

So I started imagining a model:

Unknown Liquid (concept idea)

Not a real liquid, but a system where:

state is not fixed (solid / liquid / gas all possible)
properties keep changing
small changes can create large effects

We can think like:

Viscosity idea (simple version)

Instead of constant viscosity:

V = V(\text{time}, \text{pressure}, \text{internal state})

Meaning:

it is not fixed
it depends on what is happening inside

6. The Big Bang connection I was trying to imagine

What if the Big Bang was not an explosion from nothing, but a transition inside such a system?

Like:

a sudden phase change
instability point
collapse → expansion

Not a liquid literally, but something that behaves like:

unstable medium
phase-changing system

7. Where I am unsure (honest part)

I don’t know if this is physically correct.

Because:

we don’t have evidence of such a medium
modern physics already uses fields, not liquids
many assumptions here are based on analogy, not measurement

But still, the idea feels like:

Maybe reality is not “objects moving in space”, but “states changing inside a deeper system”

8. Final understanding I reached

So my conclusion is not:

“Unknown liquid exists”

But instead:

Maybe what we call matter and universe expansion are different states of a deeper underlying system we still don’t fully understand.

Optional formula idea (very simple)

Instead of fixed physics:

\text{state} = f(\text{environment}, \text{internal instability})

\text{universe} = \text{evolving system of phase transitions}

Suggested visualization

A medium that is not fully solid, not fully liquid, where tiny changes create large structural transformations over time.
